IceCube-79 str<strong>in</strong>g analysis details<br />

23/07/12 Matthias Dann<strong>in</strong>ger IDM 2012<br />

● By compar<strong>in</strong>g signal simulation & data, cuts are<br />

placed that reduces <strong>the</strong> content of atmospheric<br />

muon events<br />

● Early analysis cuts:<br />

dedicated onl<strong>in</strong>e-filter → offl<strong>in</strong>e high-level<br />

reconstructions → first modest cuts<br />

(track quality/direction + conta<strong>in</strong>ment)<br />

● Signal event topology very different <strong>for</strong><br />

low & high WIMP mass<br />

→ f<strong>in</strong>d geometrical cut to split dataset<br />

<strong>in</strong>to 2 non-overlap<strong>in</strong>g datasets<br />
